Valve trapezoidal threads, stem nut and sliding parts of the bearing, bearing parts, gears and worm gears, meshing parts of the worm, and other coordinated moving parts all require good lubrication conditions to reduce mutual friction and prevent mutual wear. Some parts are specially equipped with oil cups or grease nipples. If they are damaged or lost during operation, they should be repaired and cleaned, and the oil paths must be cleared. Lubrication parts should be regularly refueled according to specific conditions. Frequently opened, high-temperature valves are suitable for intervals of one week to one month; infrequently opened, low-temperature valves can have longer refueling cycles.
Lubricant organic oil, butter, molybdenum disulfide, and graphite. High-temperature valves are not suitable for oil and butter, and they are lost due to high temperature melting. They are suitable for injecting a key to disulfide and rubbing graphite powder. For parts exposed to lubrication, such as trapezoidal threads, gears, etc., if grease such as butter is used, it will be easily contaminated with dust. With the use of a key word for disulfide and graphite powder lubrication, it is not easy to contaminate dust, and the lubrication effect is better than butter. Graphite powder is not easy to smear, and it can be used with a little oil or water-synthetic paste. Oil-filled sealed plug valves should be filled with oil for a specified period of time, otherwise they are susceptible to wear and leakage.
